CASH-REGISTER.

Specification of Letters Patent.

Patent-ed May 21, 1912.

' Application filed May 25, 1907. Serial No. 375,665.

rate receptacles or compartments, so thatany errors or mistakes in making change, or in depositing the money received, can be traced to the clerk making such mistake.

The object of. the invention is to provide improved means whereby the particular ope 'ated clerks element of the machine must correspond to the cash receptacle opened, or otherwise such misoperation is at once apparent to the proprietor and the remaining clerks. I

Another object of the invention is to provide an improved alarm mechanism which will be put in operation uponthe initial operation of the machine, and will not be put out of operation until all the different corresponding elements of the machine have beenproperly operated.

lVith these and incidental objects in view, the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are setforth in appended claims and a preferred form of embodiment of which is hereinafter specifically described with reference to the drawings which accompany and form par of this specification.

Ot said drawings: Figure 1 represents a transverse section through a machine of the type shown in the patent. to Cleal and Reinhard No. 580,378, issued April 13, 1897., with my improvements applied thereto; the top of the frame and a portion of the cash drawer casing being broken away. Fig. 2 represents a detail side elevation of the operating handle and driving gear, together with the machine lock; and Fig. 3 represents a diagram of the wiring and the diiierentcircuits. including the main circuit breaker, connected to the rotation shaft of the machine.

In machines at present on the market. it-

is customary to provide a series of clerks keys which, when depressed, determine the indicator to he set, the type character to be printed, and unlock the machine. These keys, which are termed the clerks keys, also control the opening of the different cash receptacles or drawers; these drawers being opened upon the regular operation of the machine and according to the key depressed.

Inv the present invention there is no me chanical' connection whatever between the clerks keys or setting elements and the different cash drawers or receptaclesmnd either one or the other may be operated without operating the other. The electrical alarms,

however, are so arranged that when a cen tain clerks key is depressed, the A key for instance, an alarm will start to ring and will continue to ring until the machine operated. Further, the alarms are so arranged that should a cashdrawer be first opened,

an alarm will be setin operation and will. continue in operation until the corresponding clerlrs keyis depressed and the machine operated. If a clerks key is first depressed and the wrong cash drawer opened, and the 0 machine operated, the alarm will continue to ring andwill be an indication to the proprietor and remaining clerks thatthe machine has been improperly operated.

Further, the tones of the alarm bells being different, will indicate to the several clerks just whichcash receptacle has been improperly opened.

The keys 1 are arranged to be latched in their depressed position by a detent 2 pivoted upon a shaft 3. A. lug l projecting laterally from the detent 52' engages an incline portion of a pawl 6 secured to a transverse shaft 7, and rocks said shaft whenever the detent is oscillated by thedcprcssion of any shoulder 9 of a cut out portion 10 of a di.-k 1G6 11 by a spring 11. This C ;k secured to the side of a gear 12 which is driven in the direction of the arrow. Fig.

p by a gear 13, which meshes with the gear 12 and also with a pinion 1e secured to the operating handle 15. A gear 16 secured to one end, of a transverse Shaft 17, meshes wun the aiorementinned gear 12.

It will be seen from the trn' Pg'oin description that the ope *ating handle is normally locked and is only released upon the operation of one of the keys 1. i

Each of the keys 1 has a laterally proecting pin 18, which when the key is depressed engages a pawl 19; pivoted to an arm 20, which in turn is pivoted to the frame of the machine, as at 21, and forces said arm downwardly against the tension of its spring 2-2. The inner end of each arm is normally in engagement with a contact plate 23 secured to the machine frame 24; each of the arms 20 and the contact plate 23being suitabl 1 insulated from said frame. When the inner end of one of the arms 20 is forced pose of which downwardly by the depression of its key, it is carried out of engagement with the contact plate 23 and into engagement with similar contact plate 25 also suitably mounted upon the frame of the machine. It is to be understood that for every key 1 there is an arm 20 and for every arm 20 there are contact plates 23 and 25. Adjacent to each of the arms 20 is an electromagnet- 25 the purpose of which will be hereinafter described. The pawls 19 pivoted to the arms '20 are prevented from turning by pins 26 when the key pins 18 are depressed, but are free to rock about their pivotal points against the tension of light springs 27 when the key pins are returned to their normal outward position.

Each of the cash drawers 28, of which there are to be as many as there are clerks keys 1, is provided with a pull 29 which covers the outer end of a latch 30 pivotally mounted within an opening 31 formed in the front partition of each cash drawer. The upper end of the latch 30 is forced into a recess 32 of a partition 32 by a leaf spring 33, thereby preventing the accidental opening of the cash drawer.

To the rear end of eachcash drawer is fastened an L shaped arm 3 1, the rear end of which is of insulating material. This insulated portion, when the casa draw-er is closed, is arranged to spread apart two contact plates 35 and. 36 which are mounted upon an insulated block 37 secured to the partition 82. Also mounted in the rearof each cash drawer 28 is a contact block 38, a magnet 39, pivotally mounted armature 10 and an electromagnetic bell 11, the purwill be hereinafter explained. Secured to the shaft 17 see Fig. 1, is a disk 12 equipped with a notch 4:3 which permits the spreading apart of the contact plates 4A and 15 once upon eacl; revolution of the disk as. The contact plates 44 and 45 are mounted upon an insulated block as suitably secured to the machine frame.

Referring to Fig. 3, the different circuits and. methods of operation will now be described, Assuming that the clerk to whom the upper key and cash drawer are assirmei has made-a sale, he goes to the maoser/es chine and depresses the keys representing the amount of the purchase and his initial key; the operation of the latter key by its pin 18 will force the arm 20 out of engagement with the contact plate 23 and into contact with the plate 25, thereby ringing the bell 11 located in the rear of the upper cash drawer by forming the following circuit: from the battery 51 to wire 50, contacts 4A: and 45, wire 49, upper magnet 25 wire 17,

contact 25, switch arm 20, wire 54, upper bell 41, wire 53, magnet 89, and over wire 52 back to the battery. The arm 20 carries an armature 20 which holds the inner end of the arm in contact with the plate 25 as long as the magnet 25 is energized, regardless of the position of the key pin 18. The next thing for the clerk to do is to open his cash receptacle, deposit the amount of the sale, closethe cash drawer and then turn the handle 15. Near the end of the revolution of the disk 12 secured to the shaft 17 the cut awaypcrtion 13 of said disk will allow the temporary spreading apart of the contact plates 14 and 45, which will deenergize the magnet 25 allowingthe spring 22 to force the arm 20 out of contact with the plate 25 and thereby break the bell ringing circuit. The inner end of each of the arms 20 is flexible, so that there will be a slight give to said arm after it has been brought into contact with the plate 25 and befor the pin 18 has passed the pawl 19; this is to compensate for any wear upon said pawl" or in and thus insure a perfect contact.

If the cash drawer is opened and closed before its companion key is depressed, the circuit is made as follows: from the battery 51 over wire 57 to the contacts 36 and wire 55, contact plate 23, arm 20, wire 5 1, bell 11, i

wire 53, magnet 39and by wire 52 back to the bat-tery. When the magnet 39 is energized, it attracts the armature 10 against the tension of its spring 10 so that the inner end of said armature will engage with the contact block 38 and form the following shunt circuit when the drawer is closed: from the battery 51 over wire 57 to armature 10, contact block 38, wire 58, wire 55, and thence back to the battery over the circuit test; described. Now upon operating the clerks key corresponding to the cash drawer that has been opened and closed, it will be seen that the drawer circuit will be broken by the key pin 18 forcing the arm 20 out of engagement with the plate 23, and at the same time form the key circuit by carrying the arm 20 into engagement with the plate 25. This latter circuit is broken upon the operation of the machine as previously described. In order that the wiring forming the circuits for the second and third drawers, and their corresponding keys, may be readily traced, the same numera s are used, with the addition of the exponents BEST AVAILABLE COP lb and respectively, as were utilized in describing the circuits for the first drawer and key. n It W1'll be seen from the foregoing descr" r tionthat there are several methods or 11'l0(..

of operation, all of which are proper in the operation of this particular machine. First, pressthe proper clerks key; second. open the'cash drawer, make the change and close the drawer again, and third, operate the machine. Thesecond means of operation is, to first open and shut the cash drawer, neXt press the clerks key and finally operate the maclnne. hen there is a charge transao i101 or any other transaction not requn'ing cration oi"? the machine; and it a cash the clerl: has opened drawer opened after this turning of the handle, an alarm will always be set in op eration and will not be again arrested until the proper clerks key is operated and the machine handle turned.

The invention provides means whereby the operator may suit his own conveniei'icc in the method of operation of the machine. It desired, he may first open the cash drawer, make change and. then close the drawer. This will start a particular alarm, and unless he operates the corresponding clerks key the alarm will continue to sound.

l'l he so desires, he can first operate the clerks key, then open his cash drawer, make change and close the drawer, which will still leave the alarm ringing, and linally turn the handle to momentarily break the circuit. The operator is not compelled, in any of these operations, to follow any certain sequence of movement or to open a cash drawer corresponding to a clerks key depressed: but it he docs not properly operate the mechanism as above described, an, alarm which has been set in operation to indicate which clerk is at the machine, will be left in operation and thus indicate to all concerned that the clerk at the machine has not properly operated it.

If a cash drawer has been opened not con responding to the depressed key, the alarm can only be stopped by the clerk operating the machine, and then dept-c singthe key corresponding to the previously opened cash receptacle. and operating the machine-a secondtime. .Bythis method of manipulation the clerk is in great danger of being it. as not only will the alarm annoiulc the wrong dr the .ltli:-l indicator will also disclose/th s to the other clcr s and the customers i in the stm'e.

The clerks" lzcys beginning at the topv otthe bank. .(11'l8 i101l il to the cash receptaclessimilarly located Within the cabinet. As-

the invention is shown the clerks keys perform the function of releasing the operating mechanism, and controlling alarm devices only, but it will be readily understood that in practice these keys are also used to determine the setting of an indicator and a printing device to selected positions, as described in the cited patent. These keys, therefore, perform the function of-selecting the proper alarm device and other parts of the mechanism for operation, and it is to be understood that the invention contemplates the use of. any form of manipulative devices which have a selective action such as outlined.

While the form of mechanism here shown and described, is admirably adapted to fullil the objects primarily stated, it is to be understood that-it is not intended to confine the invention to the one form of embodiment herein disclosed, for it is susceptible ot embodiment in various forms all coming within the scope of the claims which follow.
